Description

TECHNICAL FIELD

[0001] The utility model relates to diamond cutter production field especially, relate to a diamond cutter head production uses feeding device. BACKGROUND

[0002] Diamond saw blade is the tool of cutting various natural stone, and diamond cutter head is the working main body of diamond saw blade. Diamond cutter head is composed of diamond and matrix binder. Among them, diamond belongs to superhard material, and mainly bears the function of cutting stone in cutter head. The matrix binder is composed of metal single element powder or metal alloy powder, and its role is to hold diamond and ensure the position stability of diamond in the working process. For different use environment, the grade of diamond and the formula of matrix binder will change. In the production process of diamond cutter head, metal powder, diamond and lubricant are mixed into raw materials, and an automatic cold press is needed to press the raw materials into a compacted body with certain density.

[0003] The prior art CN202222076127.4 discloses a kind of new cold pressing equipment tool. It includes hopper, feed pipe, tool table, base, control box, blanking assembly, feed pipe is nested in the bottom end of hopper, tool table back side is provided with pressurizing system, blanking assembly includes docking disc, transmission pipe, mounting disc, pipe cylinder, docking disc is welded with transmission pipe, transmission pipe is welded with mounting disc, transmission pipe and pipe cylinder inside are through, pipe cylinder is equipped with three, pipe cylinder is communicated with hopper by feed pipe, docking disc is separated by partition sheet. The scheme makes the original single powder material pressing change into the present two or more kinds of powder material mixed pressing. But there are still the following problems:

[0004] 1. In the production process of diamond tool blanks, the scraper box first moves from the rear of the mold cavity to the top of the mold cavity. Then, the mold cavity falls, and the raw material falls with it due to gravity. The scraper box then vibrates slightly back and forth twice to allow more raw material to enter and fill the gaps left by the raw material entering the mold cavity. The scraper box then retracts to its original position, simultaneously leveling the raw material on the mold cavity. The punch on the cold press then descends to press the raw material into shape. This feeding method causes the loose density of the raw material in the mold cavity to gradually increase along the scraping direction. Furthermore, the sloping structure of the scraper box, which results in a pressure on the raw material that is smaller at the front and larger at the back, exacerbates this situation. This affects the pressure on the raw material in the mold cavity during pressing, leading to thickness differences at both ends of the blank and insufficient edge strength. Especially when using a double-hole mold to produce heavy diamond tool blanks, the mold cavity is deep. During the loading process, there will be a certain friction between the raw materials, which will affect the speed at which the raw materials enter the mold cavity. The scraper box is controlled by a cam and the loading time cannot be adjusted. Therefore, there will be uneven distribution of the loose density of the raw materials in the mold cavity. In particular, the corner positions on the adjacent sides of the two holes often have low loose density or incomplete material filling, which leads to insufficient edge and corner strength of the blank.

[0005] 2. During the production of diamond tool heads, workers need to judge the amount of raw material remaining by tapping the scraper box and listening to the sound. This operation relies heavily on experience and is highly subjective. When multiple machines are running simultaneously, negligence or misjudgment can easily lead to insufficient raw material and continued production, resulting in a large number of defective products and increased rework costs. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a feeding device for the production of diamond cutting tools. By using a separating component, it ensures that the material feeding of the two mold cavities does not interfere with each other, thereby improving the problems of insufficient material filling at adjacent corners of the double-hole mold, uneven blank thickness, and low edge strength of the blank. Furthermore, by setting a transparent observation window to replace the traditional knocking judgment method, it allows for intuitive monitoring of the remaining material, reducing the mixing of defective products due to misjudgment and improving production stability.

The pusher plate can divide the feeding chamber into two halves. The upper plate of the scraper box is equipped with a transparent observation window, through which the amount of raw material in the scraper box can be viewed.

[0013] Preferably, a waist-shaped hole is arranged on the separation plate in the vertical direction, and the separation plate is adjustably fixed on the partition connecting piece through the waist-shaped hole and the adjusting nut.

[0014] It should be noted that the separation plate is provided with a waist-shaped hole (an oblong through hole) in the vertical direction, which is aligned with the threaded hole on the partition connecting piece, and the adjustable fixing of the separation plate is realized through the adjusting nut (such as a butterfly nut or a hexagonal nut); the separation plate can slide up and down along the waist-shaped hole to adjust the vertical height thereof and adapt to the sealing rubber strips of scraping boxes of different heights.

[0015] Preferably, the pushing plate is connected with the partition assembly through a positioning connector, which is L-shaped as a whole, and one end of which is fixed on the partition assembly and the other end of which is arranged perpendicularly to the partition assembly and can be used to fix the pushing plate.

[0016] It should be noted that the positioning connector and the partition plate can be fixed on the partition plate by welding or detachably fixed on the partition plate by nuts; one end of the L-shaped positioning connector is fixed perpendicularly to the partition assembly and the other end thereof extends to the central region of the discharging cavity to form a stable cantilever structure, which provides a stable mounting basis for the pushing plate; in the scraping box, the flow of raw materials will generate a certain impact force and vibration, and if the pushing plate is not fixed firmly, displacement and shaking may occur, which affects the pushing effect of the raw materials, and the L-shaped positioning connector can stably connect the pushing plate to the partition assembly to ensure that it always maintains the correct position in the complex working environment and continuously and stably plays the role of separating and guiding the raw materials.

[0017] Preferably, a waist-shaped groove is arranged on the pushing plate in the vertical direction, and the pushing plate is adjustably fixed on the positioning connector through the cooperation of the locking nut and the waist-shaped groove.

[0021] Preferably, the transparent observation window is made of transparent acrylic material and is sealingly connected with the scraping box through sealing glue.

[0022] It should be noted that the transparent acrylic material has excellent light transmittance, and the light transmittance can generally reach about 92%, which enables the operator to clearly observe the amount and state of the material in the material scraping box. Compared with other materials, acrylic can effectively reduce visual errors while providing a clear view, ensuring that the operator can accurately determine the material level and timely supplement the material to avoid affecting production due to insufficient material and ensure the continuity and stability of production; and the transparent acrylic material is light in texture, easy to process and install, and the use of sealant for connection operation is relatively simple when installing the observation window, without the need for complex tools and technology, which can save installation time and cost.

This deformation enables the material brush rubber to closely fit the surface of the mold, filling the possible small gaps between the material scraping box and the mold, thereby effectively preventing the material from leaking out from the bottom of the material scraping box. Avoiding material leakage not only ensures the accuracy of the material filling amount in the mold cavity and the stability of the tool bit product quality, but also reduces material waste and production cost.

[0025] Preferably, a vibrating device is arranged on the material conveying pipe, which can vibrate the raw materials in the material conveying pipe.

[0026] It should be noted that in the production of diamond tool bits, the raw material is usually in powder form, which is easy to accumulate and agglomerate in the material conveying pipe, affecting normal discharging. When the vibrating device is working, high-frequency vibration will be generated. This vibration can effectively destroy the friction and adhesion between the materials, so that the materials can overcome the adsorption force of the pipe wall under the action of vibration and maintain good fluidity, smoothly enter the material scraping box through the material conveying pipe, prevent the material from blocking the material conveying pipe, and ensure the continuity of the feeding process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1

[0039] like Figures 1-4 As shown, a feeding device for diamond tool tip production includes: a feeding pipe 1 and a scraper box 2, wherein the feeding pipe 1 and the scraper box 2 are connected to form a feeding channel;

[0040] The scraper box 2 has a detachable dividing component 3 on its lower inner side along its scraping direction. The dividing component 3 divides the lower outlet of the scraper box 2 into two feeding chambers. The feeding chamber is provided with a pusher plate 4. The pusher plate 4 is symmetrically fixed on both sides of the dividing component 3 and is perpendicular to the dividing component 3. It can divide the feeding chamber into two halves. The upper plate of the scraper box 2 is provided with a transparent observation window 21, through which the amount of raw material in the scraper box 2 can be viewed.

The two ends of the separating plate connector 33 are fixed to the inner wall of the scraper box 2 by the C-shaped separating plate positioning clip 32. The separating plate 31 is symmetrically arranged on both sides of the separating plate connector 33 along the same axis.

[0042] The partition plate 31 has a waist-shaped hole 311 along the vertical direction, and the partition plate 31 is fixed to the partition plate connector 33 in an adjustable manner through the waist-shaped hole 311 and the adjusting nut 34.

[0043] The pusher plate 4 is connected to the separator component 3 via a positioning connector 5. The positioning connector 5 is L-shaped in general, with one end fixed to the separator component 3 and the other end set perpendicular to the separator component 3, and can be used to fix the pusher plate 4.

[0044] The pusher plate 4 is provided with a waist-shaped groove 41 along the vertical direction. The pusher plate 4 is adjustablely fixed to the positioning connector 5 by the cooperation of the locking nut and the waist-shaped groove 41.

[0045] The transparent observation window 21 is made of transparent acrylic material, and it is sealed to the material feeding box 2 with sealant.

[0046] The scraper box 2 has a sealing groove 6 on its bottom surface around its four sides. The sealing groove 6 has a continuous closed-loop structure and a material brush rubber sheet 8 is provided inside it with an interference fit.

[0047] The working principle and use method of the feeding device for producing a diamond tool bit are as follows:

[0048] The feeding device for producing a diamond tool bit comprises a feeding pipe 1 and a scraping box 2. The mixed raw materials flow into the scraping box 2 from the feeding pipe 1 under the action of gravity, forming a continuous raw material conveying path, providing a stable conveying channel for the raw materials, ensuring the smoothness of the feeding process, and being the basis for the normal work of the whole feeding device. The partition plate connecting piece 33 in the partition assembly is fixed to the inner wall of the scraping box 2 through the C-shaped partition plate positioning clamps 32 at both ends, providing stable support for the partition plate 31. The partition plate connecting piece 33 in the partition assembly 3 is fixed to the inner wall of the scraping box 2 through the C-shaped partition plate positioning clamps 32 at both ends, providing stable support for the partition plate 31. The partition plates 31 symmetrically arranged on both sides of the partition plate connecting piece 33 divide the scraping box 2 into two independent discharge cavities. After the raw materials enter the scraping box 2, the partition plate 31 prevents the raw materials from flowing freely between the two discharge cavities, so that each discharge cavity corresponds to the feeding port of a mold, realizing the preliminary distribution of the raw materials, solving the problem of mutual extrusion and mixing of the raw materials in the traditional feeding mode, especially avoiding the filling defect caused by the mutual influence of the raw materials at the adjacent corners of the double-hole mold, improving the accuracy and uniformity of the raw material filling, and further improving the quality of the tool blank. The transparent observation window 21 is made of transparent acrylic material, is installed on the feeding pipe 1 at the upper end of the scraping box 2, is sealed and connected with the feeding pipe 1 through sealing glue, and directly observes the quantity and state of the materials in the scraping box 2 without opening the device by using the high light transmittance of the acrylic material. The operator can monitor the material quantity in real time, avoid the tool quality problem or production interruption caused by insufficient materials, and is more intuitive and accurate compared with the traditional knocking judgment method, reduces the mixed substandard products caused by misjudgment, ensures the continuity and stability of production, and improves the production efficiency.

[0049] In use, first select the appropriate partition plate 31 and push plate 4 according to the mold type, fix the partition plate connector 33 to the inner wall of the scraping box 2 through the C-shaped partition plate positioning clamp 32, install the partition plate 31 on both sides of the partition plate connector 33, and preliminarily fix it through the waist-shaped hole 311 and the adjusting nut 34. The fixed end of the L-shaped positioning connector 5 is locked on the partition assembly 3 through a bolt, and the push plate 4 is inserted into the free end of the L-shaped connector and preliminarily fixed through the waist-shaped groove 41 and the locking nut. Loosen the adjusting nut 34 on the partition plate 31, slide the partition plate 31 up and down along the waist-shaped hole 311 according to the requirements, adjust its vertical height, tighten the adjusting nut 34 again to ensure that the partition plate 31 is fixed in position and perpendicular to the partition plate connector 33. Then loosen the locking nut on the push plate 4, slide the push plate 4 up and down along the waist-shaped groove 41, adjust the gap between the end of the push plate 4 and the bottom of the scraping box 2 to meet the requirements, and then tighten the locking nut to ensure that the push plate 4 is fixed. Complete the assembly of the feeding device, then use a bolt to firmly install the feeding device on the cold press machine tooling table, ensure that the bottom of the scraping box 2 is parallel to the surface of the mold, and check the sealing groove 6 around the bottom of the scraping box 2, ensure that the brush rubber 8 is complete and has no damage, and one end of the feeding pipe 1 is connected to the outlet of the hopper, ensuring that there is no gap at the connection (if necessary, use sealing glue to reinforce); Put the mixed diamond and metal powder raw materials into the hopper, start the cold press machine, the raw materials enter the scraping box 2 through the feeding pipe 1, the scraping box 2 moves back and forth with the tooling table, and the raw materials are evenly guided into the mold cavity under the guidance of the push plate 4, and the scraping box 2 moves back and forth with the tooling table; As the equipment runs, the scraping box 2 moves towards the mold under the drive of the equipment to scrape the material. During the scraping process, the brush rubber 8 on the bottom of the scraping box 2 is in close contact with the surface of the mold. Due to the elasticity of the brush rubber 8, it tightly adheres to the surface of the mold under pressure, thereby preventing the material from leaking from the bottom of the scraping box 2. At the same time, the partition assembly 3 and the push plate 4 begin to play a role, the partition assembly 3 separates the material in the scraping box 2 into two discharge cavities to avoid interference between the two mold cavities; The push plate 4 further evenly separates the material in each discharge cavity, guiding the material to enter each mold cavity of the mold evenly; During production, the operator needs to continuously monitor the amount of material in the scraping box 2 through the transparent observation window 21. Once the amount of material is found to be close to the set minimum value, the raw material is added in time to ensure the continuity of feeding and avoid unstable tool quality or production interruption due to insufficient material. At the same time, pay attention to the pressing situation of the tool bit. If quality problems such as uneven thickness and large weight difference of the tool bit are found, check whether each part of the feeding device is working normally in time. If necessary, adjust the partition plate 31, push plate 4 and other parts again.
